Abstract: PURPOSE: To decrease the number of power supply facilities and simultaneously perform spot welding of multiple points with simplified equipment by providing plural welding guns on the jig base side, pressurizing the works and successively supplying the power through contacting with the contact gun units.  
     CONSTITUTION: The works W are placed on jig bases 4, and welding guns 6 for respective depressing point positions are turned to press and hold the works W to stationary electrodes 5 with their respective movable electrodes 9. The power supply elements 12 of the respective welding guns 6 are turned together with pressing arms 8 to form the combinations with the power supply terminals 12 erected in the positions away by the same distance as the distance between contact guns 15. Thence, with the works W held pressed, the robot is operated to successively oppose a pair of the contact guns 15 to each of the power supply terminals 12. Arms 17 are opened and closed by the operation of air cylinders 16 to successively press and contact the contact elements 18 to and with the power supply terminals 12, whereby the power is supplied. Thereby, the multiple depressed points are successively spot- welded.

Title: Toner supply method and device therefor
Inventor: MASUDA NOBUCHIKA
IPC: G03G15/08
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To always stably electrify toner even in the case of image formation in which the output size of a transferred image is different by changing a supply cycle when density control is continued for a specified time in the same area so that the concentration control may progress toward an area including a reference value. SOLUTION: A toner density sensor 49 detects toner density in a developing device while the developing device is being actuated, and outputs a detection signal to a control means 60. The control means 60 allows an arithmetic circuit 63 to arithmetically calculate in what area the toner density is positioned from analog voltage as the detection signal, and fetches the cycle of toner supply corresponding to a signal showing the obtained area and a signal showing the size of transfer material transmitted from a control panel, etc., from a storage means 61, and drives a driving motor 62 based on the obtained data. The reference value of the toner density is set in the control means 60.  When the toner density in a certain area is continuously detected for the specified time, the control means 60 controls to change the setting to a next area one by one so as to aproach to the area including the reference value.

Title: Vibrational feeder
Inventor: AKAMA MASARU
IPC: B65G27/26
Filed: 1979-09-25
Abstract: PURPOSE: To provide a vibrational feeder in which those portions other than the portion of a vibrating bowl where articles to be transported are received can be protected against impact forces exerted by article put into the bowl, by fixing an article receiving member in the bowl by the intermediary of damper.  
     CONSTITUTION: In the vibrational feeder shown in the drawing, a fixing plate 12 of a vibrating bowl 10 is mounted on a base plate 14 by the intermediary of plate springs 34. Vibration is imparted to the plate 12 by a vibrator for aligning and feeding articles on a carrier track in bowl 10. In the bowl 10, an article receiving member 90 is fixed by the intermediary of rubber springs 92 at a position under a hopper 94. With such arrangement, impact forces exerted when articles are put into the bowl can be absorbed at the member 90, so that remaining portion of the apparatus can be protected from impact forces. Further, there is no fear of adversely affecting article aligning function of the apparatus by imparting unnecessary vibration to the vibrating system.

Title: Production of chlorosulfonated polyethylene
Inventor: NARUI MAMORU
IPC: C08F8/38
Filed: 1982-07-16
Abstract: PURPOSE:To obtain the titled polyethylene inexpensively in good efficiency, by dissolving polyethylene in a halogenation solvent, chlorinating the polymer with chlorine, then chloro-sulfonating it with sulfuryl chloride and, after feeding chlorine, further reacting the polymer. CONSTITUTION:Polyethylene is dissolved in a halogenation solvent (e.g., carbon tetrachloride) to form a solution of about 2-20wt% concentration. This solution is chlorinated with chlorine in the presence of an initiator (e.g., benzoyl peroxide). When the chlorination degree has reached a predetermined value, a promotor (e.g., pyridine) is added, and a predetermined amount of sulfuryl chloride is added, and the chlorosulfonation is effected at 50-100 deg.C. Then, chlorine is fed again into the system, and the chlorination is continued until the chlorination degree has reached the final desired value to obtain the purpose chlorosulfonated polyethylene. Thus, the working efficiency can be improved because it becomes possible to eliminate the need of recovering sulfur dioxide formed as a by- product when sulfuryl chloride is reacted.

Filed: 1987-05-20
Abstract: PURPOSE:To keep demand constant at all times regardless of an optical output, and to hold the temperature of a laser chip at a fixed value at all times by forming a region capable of consuming power near a semiconductor laser on a substrate. CONSTITUTION:When large currents are flowed between an electrode 101 and a substrate 114 and the edge face section of a laser is broken, a region in which only the power consumption of a non-radiative region is conducted is formed between the electrode 104 and a substrate 112. In a two beam type semiconductor laser array having such structure, a semiconductor laser LD3 driven by an electrode 103 is used for writing, a semiconductor laser (LD2) driven by an electrode 102 is employed for reading, and the region D1 in which power is consumed is used for compensating a temperature by the electrode 101. When currents in magnitude the same as the driving currents of the LD3 are flowed through the D1 when the LD3 is turned OFF, the temperature of a chip is kept constant at all times regardless of the ON-OFF of the LD3, and an optical output from the LD2 is not modulated by the driving currents of the LD3.
